GLOBAL HALLOYSITE MARKET SIZE AND SHARE ANALYSIS - GROWTH TRENDS AND FORECASTS (2024-2031)

The halloysite market size is expected to reach US$ 63 Mn by 2031 from US$ 40.4 Mn in 2024 at a CAGR of 6.5% during the forecast period.

Halloysite is a naturally occurring clay mineral composed of aluminum silicate. It exists in two distinct polymorphs - the common halloysite-7Å and the less common halloysite-10Å. Halloysite-7Å has a tubular morphology with an inner diameter of 15-100 nm, length of 0.5-10 μm, and outer surface consisting of siloxane groups. This gives it a high surface area and makes it suitable for use as a carrier for drugs and other chemicals by adsorption on the outside and inside surfaces as well as its lumen. Its negatively charged lumen and positively charged outer surface allows it to encapsulate drugs, fragrances, pigments, and others through ion-exchange. This halloysite polymorph is also being researched for its potential in creating bone scaffolds and tissue engineering applications due to its ability to mimic the morphology of hydroxyapatite.

However, halloysite-10Å has a planar morphology consisting of silicate layers separated by water interlayers, resembling kaolin. While it does not have the same tubular properties as halloysite-7Å, it still finds use as a convenient nanocontainer for slow-release applications by storing compounds between its layers. Both polymorphs have advantages over synthetic alternatives in various applications due to their low-cost natural abundance and biocompatibility.
